| 英文摘要 | Highly-dispersed LiFePO4/C composite with micro-leaf structure was synthesized by a facile citric acid-assisted hydrothermal method in this study. Crystal structure and morphology of samples were investigated by XRD, FTIR, SEM, HR-TEM and selected area electron diffraction (SAED). The characterization results indicate that citric acid accelerates the formation of leaf-like LiFePO4/C composite. The as-prepared leaf-like LiFePO4/C composite with an enlarged (010) plane has high dispersibility. By comparing the electrochemical properties of the LiFePO4/C particles in our study, the LiFePO4/C micro-leaves exhibit larger discharge capacity and better rate performance, which deliver a discharge capacity of 158 mAh.g(-1) at 0.1C and 126 mAh.g(-1) at 5C. The enhanced performance perhaps is attributed to the reduced Li-ion diffusion paths along the [010] direction and larger Li-ion diffusion coefficient. |
